... the TCP/ IP software isolates such differences and makes the communication system independent of the underlying hardware technology. TSuch long delays result from WANs that communicate by sending ... advantage of packet- switching is that multiple communications among computers can proceed concurrently, with intermachine connections shared by all pairs of computers that are communicating. ... destination address easily. A sender must know the address of the intended recipient, and must place the recipient's address in the destina- tion address field of a packet before transmitting...
... were found, declare a routing error; Figure 10.8 The unified IP routing algorithm. Given an IP datagram and a routing table with masks, this algorithm selects a next hop router to which ... subdivision flexible by allowing one to specify the exact number of bits that correspond to a prefm. To summarize: Classless addressing, which is now used by ISPs, treats IP addresses as arbitrary ... example demonstrates a technique often employed with unnumbered net- works. Rather than leaving the next hop empty, it is filled with one of the IP addresses assigned to the next-hop router...

The vendor modified its standard IP routing software to make the subnet ... hardware ad- dress. The third technique, a TCPnP standard called subnet addressing, allows a site to share a single IP network address among multiple physical networks. All hosts and routers...
